tained substantially uniform with relation to the body of the machine, regardless of the movement of the planes about their axes.

In rear of the main planes there is a pair of supplemental or rear planes H, each pref erably resembling in shape the main planes,

but of considerably smaller size, said supplemental planes being hin ed at their forward edges on substantial y horizontal axes or hinge bearings I. These hinged bearings are conveniently mountedv on a cross piece or transverse bearer K carried by the main frame, and in order that the rear planes 4may have-normally a slight angle with relation to each other, or converge downwardly,

the bearings are set at a. slight angle to each other, as will be understood from an inspection ofFig. 3. The rear or supplemental planes H are provided witl. vertical shafts l, from the ends of which braces H extend outwardly to the frame of the planes for bracing the same, and these shafts are preferably utilized as the means whereby the controlling attachments' or connections may be -made with the planes.

Although it is contemplated that under certain clrcumstances it may be necessary or, desirable to have manual control of the lanes which will enable them to be moved independently in the normal operation of the machine, it is designed that the control of the planesshall be interdependent and set on the shaft O with relation to cach other that the operator shall have the means at hand whereby he can, through the manipulation of the same handle, simultaneously 4set both the main and supplemental planes and at its lower'end with a cross head or T M2. Extending rearwardly from opposite ends ofthe cross lhead M2 are connect-ing ,rods or links N, which at their rear ends are jointed to crank arms Nf on the engine frameY or other suitable portion of the main frame, and in, addition 'to thecrank-arm N they carry;relativelyV long crank, arms .0

connected bv links-0 with themain planes,

and relatively short crank'arms l connected by rods or links P. with the upper ends of the brace shafts of the rear or supplemental planes. The crank arms 0.', and P are so that a rotation of the shaft in one direction will swing the main planes forwardly and the rear planes downwardly, while a lmovement of the shaft in the opposite direction will swing the main planes rearwardly and the supplemental planes upwardly. With the construction as described, therefore, the operator may,.by pulling directly backward on the operating lever, swing the main planes toward the front of the machine, and

turn the supplemental planes down and by pushing forwardly on the saidlever, all ot' said planes will be swung in the opposite direction, to wit:-the main planes rearwardly andthe supplemental planes upwardly.

By turning the operating lever in its bear in it is obvlous that the main plane on one si e may be swung in one direction andthe main plane on the other side in the opposite direction, but in such case the rear or sup Elemental planes on each side are moved as efore described with relation to the movement of the forward plane, that is to say, it one main plane is swung forwardly and the opposite main plane rearwardly, the supplemental plane of one side is swung down wardly, and that on the other side upwardly, respectively.

From the foregoing it will be readily seen that as the forward planes swing ahead of the center of gravity, the rear planes deflect downwardly and add to the surface of the sustaining power of the machine, so that the sustaining surface is still at the rear of the center of gravity. Furthermore, it will be seen that while the rear planes deflect downwardly from their neutral position so that their under surface becomes active, the angle of deflection does not equal that of the lorward planes. Abnormal movement of the rear planes such as may he necessary or dcsirablc for rising from the ground, is not provided for by the mechanism illustrated herein, nor is it thought that the mechanism for accomplishing these ends would add anything tothe clearness of the disclosure,

and hence the same has been omitted;

Vlith the arrangement described, when it. becomes necessary to steer the machine. to the right or left this may be accomplislicil `by moving the forward planes, one forwardly and the other backwardly. the rfnr planes at the same time correspondingly :uljusting themselves to keep the balance of the machine, and the machine will swing in the direction in which the center of gravity is forward of the sustaining center of the eral balance of the machine is maintained or restored without increasing the angle incident to the line of flight, as in other aeroplanes, as heretofore constructed, `and conseuently there is no dragon the machine to becounteracted by the opposite movement of a rudder, such as has heretofore been cmploycd,l butwhich may be entirely omitted with the present construction. For example.
